Pipe Flange System
Piping flange imatanthawuza ma flange omwe amagwiritsidwa ntchito poyika mapaipi poyika mapaipi, ndipo amatanthauza zolowera ndi zotuluka za zida zikagwiritsidwa ntchito pazida.Pali mabowo pa flanges, ndipo mabawuti amapanga ma flanges awiri olumikizana mwamphamvu.Ma flanges amasindikizidwa ndi gaskets.Flange imagawidwa mu kugwirizana kwa ulusi (kulumikizana kwa ulusi) flange, kuwotcherera flange ndi clamp flange.Flanges amagwiritsidwa ntchito awiriawiri, waya flanges angagwiritsidwe ntchito mapaipi otsika kuthamanga, ndi flanges welded pofuna kukanikiza oposa makilogalamu anayi.Gasket imawonjezeredwa pakati pa ma flanges awiri ndikumangika ndi mabawuti.Makulidwe a ma flange okhala ndi zovuta zosiyanasiyana ndi zosiyana, ndipo mabawuti omwe amagwiritsa ntchito ndi osiyana.Mapampu amadzi ndi mavavu akalumikizidwa ku mapaipi, magawo a zida ndi zida izi amapangidwanso kukhala mawonekedwe ofananirako a flange, omwe amatchedwanso kulumikizana kwa flange.Zigawo zonse zolumikizira zomwe zimalumikizidwa ndi mabawuti pamphepete mwa ndege ziwiri ndipo zimatsekedwa nthawi yomweyo zimatchedwa "flanges", monga kulumikiza mapaipi olowera mpweya.Zigawo zamtundu uwu zitha kutchedwa "gawo la flange".Komabe, kugwirizana kumeneku ndi gawo limodzi la zipangizo, monga kugwirizana pakati pa flange ndi mpope wa madzi, si bwino kutchula mpope wa madzi "mbali za flange".Zing'onozing'ono, monga mavavu, amatha kutchedwa "magawo a flange".

2. Malinga ndi petrochemical (SH) makampani muyezo: ulusi flange (PT), matako kuwotcherera flange (WN), lathyathyathya kuwotcherera flange (SO), socket kuwotcherera flange (SW), lotayirira flange (LJ) , Flange chivundikiro (chosasonyezedwa ).
3. Malinga ndi makina (JB) mfundo makampani: chofunika flange, matako kuwotcherera flange, mbale lathyathyathya kuwotcherera flange, matako kuwotcherera mbale mbale lotayirira flange, lathyathyathya kuwotcherera mphete mbale lotayirira flange, flanged mphete mbale lotayirira Flange, flange chivundikirocho.
4. Malinga ndi mfundo za dziko (GB): ophatikizika flanges, flanges ulusi, matako kuwotcherera flanges, khosi lathyathyathya kuwotcherera flanges, khosi khosi kuwotcherera flanges, matako kuwotcherera mphete khosi lotayirira flanges, mbale lathyathyathya flanges kuwotcherera flanges, matako-kuwotcherera mbale mbale lotayirira flanges. , mbale yowotcherera yopyapyala yokhala ndi ma flanges otayirira, mbale zokhala ndi mphete zotayirira, zophimba za flange.
WCB (mpweya zitsulo), LCB (otsika kutentha mpweya zitsulo), LC3 (3.5% faifi tambala zitsulo), WC5 (1.25% chromium 0.5% molybdenum zitsulo), WC9 (2.25% chromium), C5 (5% chromium 0.5% molybdenum), C12 (9% chromium ndi 1% molybdenum), CA6NM (4 (12% chromium zitsulo), CA15 (4) (12% chromium), CF8M (316 zitsulo zosapanga dzimbiri), CF8C (347 chitsulo chosapanga dzimbiri), CF8 (304 chitsulo chosapanga dzimbiri ), CF3 (304L) Chitsulo chosapanga dzimbiri), CF3M (316L zitsulo zosapanga dzimbiri), CN7M (zitsulo zazitsulo), M35-1 (Monel), N7M (Haast Nickel Alloy B), CW6M (Hasta Nickel Aloy C), CY40 (Inconel) Dikirani.
Njira yopanga imagawidwa m'mitundu inayi: kupanga, kuponyera, kudula ndi kugudubuza.
(1) Kuponyera flange ndi flange yopukutira
Flange yotayira ili ndi mawonekedwe olondola ndi kukula kwake, voliyumu yaying'ono yopangira ndi mtengo wotsika, koma ili ndi zolakwika zoponya (pores, ming'alu, inclusions);mawonekedwe a mkati mwa kuponyera ndi osauka mu streamline (ngati ndi kudula mbali, streamline ndi zoipa);
Ma flanges opangidwa amakhala ndi mpweya wocheperako kuposa ma flanges otayira ndipo siwovuta kuchita dzimbiri.Mapangidwe amasinthidwa, amakhala ndi mawonekedwe olimba, ndipo amakhala ndi makina abwinoko kuposa ma flange;
Kupanga kolakwika kungayambitsenso njere zazikulu kapena zosagwirizana, ming'alu yowumitsa, ndi kupangira ndalama zokwera kuposa ma flanges.
Ma forging amatha kupirira kumeta ubweya wambiri komanso mphamvu zolimba kuposa zoponya.
Ubwino wa castings ndikuti amatha kupanga mawonekedwe ovuta komanso otsika mtengo;
Ubwino wa forgings ndikuti mawonekedwe amkati ndi ofanana, ndipo palibe zolakwika zovulaza monga pores ndi inclusions pakuponya;
Kuchokera pakupanga, kusiyana pakati pa cast flange ndi forged flange ndi kosiyana.Mwachitsanzo, centrifugal flange ndi mtundu wa flange.
Ma centrifugal flanges ndi a njira yolondola yopangira ma flanges.Poyerekeza ndi kuponyedwa kwa mchenga wamba, mapangidwe amtundu uwu ndi abwino kwambiri, ndipo khalidweli limakhala bwino kwambiri.Sichimakonda kukhala ndi zovuta monga mawonekedwe otayirira, pores, ndi trachoma.
Choyamba, tiyenera kumvetsa mmene flange centrifugal amapangidwa, ndondomeko njira ndi mankhwala a centrifugal kuponyera kuti lathyathyathya kuwotcherera flange, amene amadziwika kuti mankhwala kukonzedwa mwa njira zotsatirazi:
① Ikani chitsulo chosankhidwacho mu ng'anjo yamagetsi yapakati pafupipafupi kuti musungunuke, kuti kutentha kwachitsulo chosungunuka kufika 1600-1700 ℃;
② Yatsani nkhungu yachitsulo ku 800-900 ℃ kuti mukhale ndi kutentha kosalekeza;
③ Yambitsani centrifuge, ndikutsanulira chitsulo chosungunula mu sitepe ① mu nkhungu yachitsulo mutatha kutentha ②;
④ Kuponyedwa kumakhazikika mpaka 800-900 ℃ ndikusungidwa kwa mphindi 1-10;
⑤ Kuziziritsa ndi madzi pafupi ndi kutentha kwabwino, tsitsani ndikutulutsa kuponya.
